How about "you're mistaken"?

The problem is with "You don't know what you're talking about, but I do, so let me answer your real question".

The wording used was "You’re asking the wrong question” not "You don't know what you're talking about".

I find that perfectly fine. It was slightly disingenuous to reword it.
